So, I'm playing a custom 1.6 world with Big Reactor, a bunch of mods, and GregTech as well. I'm having a little issue (not that much, but I think it's noticeable). When I mouse over the Yellorium ingot (I think it is called like such), I can see it's name : "PLEASE CHECK YOUR LOG FOR 'GT-ERR-01'", and in my log I can see :
GT-ERR-01:
[Infos] [STDERR] A Recipe used an OreDict Item as Output directly, without copying it before!!!
[Infos] [STDERR] Said Item will be renamed to make the invalid Recipe visible.
[Infos] [STDERR] Please check all Recipes outputting this Item, and report the Recipes to their Owner.
[Infos] [STDERR] The Owner of the Recipe, NOT the Owner of the Item!!!
[Infos] [STDERR] And ONLY Recipes which are OUTPUTTING the Item, sorry but I don't want failed Bug Reports.
I'll report this bug to Gregorius too, because it has a OreDict feature where when you hold one ore / ingot, it'll change to it's GregTech form. And in this case, it converts the yellorium into uranium ingot. I don't see any problem with the Cyanite or the Blutonium (this one is oredict as Plutonium).
Well, you might be thinking it's a greg derp, but the graphite ingot has the same name too! And, in this case, I can only use Graphite in the BR mods, whereas with the yellorium I can use this to create either uranium fuel rod, or Irradiant uranium (advanced solar mods).
Thank you for reading this huge mess.
EDIT : I just found this :
BigReactors -> oreYellorite uses an unknown Material. Report this to GregTech.
BigReactors -> ingotYellorium uses an unknown Material. Report this to GregTech.
BigReactors -> ingotCyanite uses an unknown Material. Report this to GregTech.
BigReactors -> ingotGraphite
BigReactors -> ingotBlutonium uses an unknown Material. Report this to GregTech.
BigReactors -> dustYellorium uses an unknown Material. Report this to GregTech.
BigReactors -> dustCyanite uses an unknown Material. Report this to GregTech.
BigReactors -> dustGraphite
BigReactors -> dustBlutonium uses an unknown Material. Report this to GregTech.
Definitively coming from Greg

Yep. I'll see if I can hunt down the "output" behavior he describes. The material thing is odd, as I just use the Iron and Stone materials; that's probably on his side.

Yope, it is! I reported him because one file that his OreDict converter adds (OreDict.log) was saying to report to GregTech.
"[Place your ingot name here] uses an unknown Material. Report this to GregTech."
It's not saying the [Place your ingot name here], just because there's a lot of material.

GregTech changes how the OreDict functions and then gripes when other mods don't follow Greg's version of it. Technically this is a GregTech issue, it's just a matter of which modders feel like supporting Greg's version or the Forge version.

In this case, the changes on my end appear to be very minor and don't harm the mod, so I'm willing to make them for the sake of compatibility.

This will be out in 0.2.10A.
